摘　　要：试验对比研究了鬼针草粉与苜蓿粉对猪的饲用价值。结果显示,鬼针草粉与苜蓿粉的粗蛋白质和粗脂肪含量均比较接近,但鬼针草粉粗纤维含量比苜蓿粉低,钙、磷含量约高于苜蓿粉。两种草粉主要营养成分的表观消化率无显著差异,但鬼针草粉的适口性较差,添加鬼针草粉10%时,对试验猪的采食量影响较小,日增重率最高(0.64%),料重比最小(2.61),为最佳添加量。添加鬼针草粉15%与基础饲料组和苜蓿粉15%组相比,试验猪采食量显著下降(P<0.05),说明采食量明显影响了日增重率和料重比。Comparative studied on Bidens bipinnata L. powder and Medicago sativa L. powder on test pig feed- ing value was conducted. Results showed that crude protein and crude fat content of two grass powder were very close, but crude fiber contents of Bidens bipinnata L. powder were lower than Medicago sativa L. powder and calci- um and phosphorus contents were higher than Medicago sativa L. powder. The main nutrients apparent digestibility of two grass powder had no obvious difference. But palatability of Bidens b^pinnata L. powder was poor. Adding 10% of Bidens bipinnata L. powder for feed intake of the pigs had less affected. Daily weight gain rates （0.64%） was the highest, and feed to gain ratio was minimum （2.61） as optimum adding amount. Adding 15% of Bidens bipinnata L. powder significantly decreased feed intake when compared with relative basal diet group and adding 15% Medicago sativa L. powder meal group. Feed intake significantly affected the weight gain rate and feed weight ratio of test pig.
